The Shimano HG93 chain is their XT level 9 speed chain designed for use with Hyperglide cassettes and chainrings. It is compatible with both mountain and road (Ultegra level 9 speed drivetrains) and it has 116 Zinc-alloy plated links.
If 8 is not enough and 10 is too many, you need 9 speed drivetrain parts.

I have been very happy with the performance of this chain. Very reliable and smooth shifting. I wish shimano would offer something like the sram quik link to make changing the chain out easier. With that said. I don't often have the need to remove it so not a deal breaker for me.
Saw a review about "not for aggressive riders"... maybe, or maybe it's installation challenges? I've ridden several HG-93s over the years, till they've worn out, never had one self-disassemble. I've used their link pins, and also used SRAM power links, with no issues. For perspective, I'm 6'2", and over the years between 203-253 lbs, I've raced, ridden endurance challenge rides (100 trail miles on a variety of trails in one day), and other challenging things. I've broken a variety of things on my bikes, including the frames, but have never had one of these break. YMMV.
I've used these chains for years and only have 1 blow out on me and I might have installed wrong. The chains go a long time without stretching. The links are smooth and don't kink. They are not noisy if lubed properly.
I switched my drive train to a single ring 9 speed. Other brands didn't cope with the big angles but this chain has been great. No problems and with the right tool they are really easy to take off to clean. I highly recommend these chains.
